Good artists copy; Great artists replicate

Node Malmö



Let's talk about replication. Database replication is probably one of the most misunderstood things in computer science. I've been in various arguments with developers about how to replicate a database in a distributed system. Some argue that mongodb's way is the best. Some argue postgres. Some prefer emailing zips of database dumps around the office.

In general, replication is a *really hard* problem. However, it is actually pretty simple if you are willing to accept some trade-offs.

This talk will be about investigating how we can make replication simpler by building specialized databases that does fewer things. Using a bunch of small npm modules we'll build a database that supports multi master replication in a couple of 100 lines of code.

Mathias was early in when it came to NodeJs and was using it as early as version 0.1.x. He is also a co-host of Copehagen Node Hackaton, the author of more than 200 modules on npm and was recently a guest on the podcast NodeUp.
